Final answer:
Mafic minerals, like olivine and pyroxene, crystallize early from magma due to their high melting temperatures, while quartz and muscovite crystallize later.
Step-by-step explanation:
The question concerns the crystallization sequence of minerals from magma, which is related to the concept of the Bowen's reaction series in geology. In this sequence, mafic minerals such as olivine and pyroxene crystallize early from a magma due to their high melting temperatures. As magma cools, the next minerals to crystallize tend to be feldspars such as orthoclase (K-feldspar) and plagioclase, followed by muscovite and quartz. Quartz is known to crystallize later and typically fills spaces after many other minerals have formed.
Considering the given choices and the nature of the minerals, mafic minerals and K-feldspar are likely to crystallize early from magma because they have higher melting points. Quartz and muscovite tend to crystallize at lower temperatures, therefore, later in the cooling process. It is important to note that feldspar crystallizes at high temperatures early in the cooling process and is associated with having straight crystal sides, which can reflect light when the specimen is rotated.
Based on this information, the correct answer is that mafic minerals would likely crystallize early from a magma.
